How do you keep blue junipers small?

Answered by Douglas Hiatt

Keeping blue junipers small can be achieved through regular pruning and maintenance. I’ve had personal experience with this as I have a blue juniper bush in my backyard that tends to grow quite vigorously. Here are some tips on how to keep them small:

1. Prune regularly: Pruning is essential to control the size and shape of blue junipers. I typically prune my juniper bush once or twice a year, depending on its growth rate. I find that early spring and late summer are good times to prune.

2. Use selective pruning: When pruning, it’s important to selectively trim back each branch’s terminal tip. This involves cutting off the topmost portion of each branch, which will reduce the length and weight of the branch. By doing this, you prevent the branches from becoming too long and eventually pulling out from the trunk.

3. Avoid drastic pruning: While it may be tempting to heavily prune the juniper bush to achieve a desired size, it’s best to avoid drastic pruning. Removing too much foliage at once can stress the plant and potentially harm its overall health. Instead, opt for gradual and selective pruning over time.

4. Shape the bush: In addition to controlling the size, shaping the bush can also help in keeping blue junipers small. This involves trimming the outer branches to maintain a compact and tidy appearance. I like to use hand pruners or shears to carefully trim the outer edges of the bush, ensuring a balanced and neat shape.

5. Remove dead or damaged branches: While pruning, it’s important to remove any dead or damaged branches. These branches not only affect the overall appearance of the bush but can also hinder its growth. By removing them, you allow the plant to focus its energy on healthy growth.

6. Monitor watering and sunlight: Proper watering and sunlight play a crucial role in the growth of blue junipers. Ensure that the plant receives adequate sunlight, as this promotes compact growth. Additionally, avoid overwatering the bush, as excessive moisture can lead to rapid growth. Regularly check the soil moisture and water only when needed.

7. Mulch around the base: Applying a layer of mulch around the base of the juniper bush can help retain moisture and regulate soil temperature. This can indirectly contribute to controlling the plant’s growth by providing optimal conditions for its overall health.

Remember, each blue juniper bush is unique, so it’s important to observe and adapt your pruning and maintenance techniques accordingly. By following these tips, you can keep your blue juniper small and well-maintained, enhancing the aesthetic appeal of your garden.
